Stability analysis for some classes of time-delay nonlinear Hamiltonian systems

A The stability of Hamiltonian systems with time delay was investigated. Using the technique of the Lyapunov direct method and the dissipative structural properties of Hamiltonian systems, some sufficient conditions are derived for the stability of several classes of time-delay Hamihonian systems. First, the stability is studied for the system with delay only in the Hamihonian function, with which the stability of a class of time-delay nonlinear systems is also investigated by Hamiltonian reahzation. Second, the robust stability is considered for a class of time-delay Hamiltonian systems which possesse time-invariant uncertainties belonging to some convex bounded polytypic domain. Finally, several illustrative examples are studied by using the proposed results. Examples show that the results are very practicable in analyzing the stability of some classes of time-delay nonlinear systems.
